14, 1940, serial No. 356,843 1 claim. (c1. 251-24) Application SeptemberThis invention relates to the class of sprinkling,

spraying and diffusing and pertains particularly to improvements insprayer devices designed primarily for use in moistening clothespreparatory to ironing. Y

The primary object of the invention is to provide a novel compactsprayer head or nozzle which is designed to be attached to a hose toreceive water directly from a domestic water supply system, the nozzlebeing so designed that the application of pressure upon an elementthereof releases a -valve diaphragm which permits the water to shift thediaphragm from its seat and dow through for discharge from the nozzletip.

Another object of the invention is to provide a spray device wherein ahead, provided with a diffusing nozzle, carries a shiftable diaphragmwhich is normally maintained upon a seat by a hand actuated handle, saiddiaphragm when rey leased by the actuation of the handle being shiftedfrom its seat to permit water under pressure to pass through the nozzlefor discharge from the tip in the form of a fine spray.

A further 'object of the invention isto provide a spraying device of thecharacter stated wherein a novel means is provided to facilitate` theready adjustment of the degree of neness of the water spray dischargedfrom the nozzle.

The invention -will be best understood from a consideration of thefollowing detailed descrip,- tion taken in connection with theaccompanying drawing forming part of this specification, with theunderstanding, however, that the invention is not to be confined to anystrict conformity with the showing of the drawing but lmay be changed ormodified so long as such changes or modifications mark no materialdeparture from the salient features of the invention as expressed in theappended claim.

In the drawing:

Fig. 1 is a top plan view of the sprayer embodying the presentinvention.

Fig. 2 is a sectional view'on the line Fig. 1.

Fig., 3 is a View in elevation of the rear end of the sprayer. Y

Fig. 4l is a View partly in section and partly in side elevation of amodified form of the sprayer.

Referring now more particularly to the drawing, the numeral I generallydesignates the body or head of the spray device embodying the presi entinvention. This body may be cast or otherwise suitably formed of anysuitable material andV it is provided with a tapered vforward endportion 3 provided to facilitate the' attachment to the head of a hoseor other suitable conduit 4 by means of which water may' be 'conveyedfrom a water supply system to the. nozzle.

In the rear of the nozzle body there is formed v nozzle 1 and this taperis made use of for securing in position in the forward end of thechamber 6, the core 9 which functions to impart a whirling motion to thewater as it issues from the nozzle aperture 1. Thisbody 9 is formed of arelatively soft metal such as aluminum or brass and the side surface isprovided with the plurality of spiral grooves or channels Ill alongwhich the water ows in passing between the body 9 and the taperedportion 8 of the water chamber wall.

The degree of neness of the spray issuing from4 the nozzle 1 may becontrolled by regulating the extent 4to which the spiral core body isforced into the tapered end 8 of the water chamber, it

being readily obvious that as the core body is forced into the taper, itwill be mashed or compressed and will reduce the size of the spiralgrooves or channels. Thus the farther the core bodyfis forced into thetaper, the ner will be the water spray issuing from the nozzle 1. A l

The nozzle passage 'I is protected from damage through the tip of thebody being struck against objects, by being set back in the tip, and theend.

l provided an annular seat I3 -for'a valvev disk I4 formed of rubber orother suitable material. This valve disk is maintained in positionadjacent to the seat I3 sovthat the portion adjacent the seat may havelimited movement relative to the seat 'permitting it to shift off of thesame, under the effect of water pressure applied thereto, the re-vtention of the diaphragm being effected by the ring I5 which is secured-to the .Wall of the recess either by a press fit or by screw threads,

2 and at its rear with the integral coupling nipple 55 as shown.

Extending throughY and from the nipple 3 is a water passageway I6 whichat its forward end is reverted, yas indicated at I'I, to open into thebottom of the annular water channel I2. Since the overall diameter ofthe water channel I2 is less than the diameter of the recess and of thevalve disk Il, it will be readily seen that the valve disk or diaphragmwhen 'pressed against the seat I3, will effectively close the channel.

' Extending longitudinally in the top of the body I is a slot I8 acrossthe rear end of which a pivot pin I9 is secured. The rear end of thisslot is in communication with the annular recess 5 and there is disposedwithin the slot the handle which is pivotally supported upon the pin I9and which has the laterally turned rear end portion v ascenso tent towhich the plug is forced into the tapered 2| which terminates in thereversely extending l linger tip 22, which is disposed substantiallyupon the axial center of the water chamber 6. Thus the linger 22 will bedisposed at the rear of the center of the diaphragm valve and when theforward end of the handle is raised to oscillate the handle on the pinI9, the linger 22 will move toward the diaphragm.

Interposed between the nger 22 and the diaphragm is a disk 23 of metalor other suitable material which functions as a 'bearing plate againstwhich the nger engages whenthe handle is oscillated in the properdirection to move the finger forwardly for the purpose of pressing thevalve diaphragm against the seat I3.

Constant application of pressure against the disk 23 and diaphragm Il bythe finger 22 is effected by placing a suitable expansion spring 24beneath the forward end of the handle 2U, locating the ends of thespring in the opposed recesses 25 and 26 formed respectively in thehandle and in the body. By this means, the spring is retained inposition and can function freely to oscillate the handle in the desireddirection to maintain the valve diaphragm upon its seat.

From the foregoing, it will be readily apparent that with the spraydevice of the present invention, a constant supply of water underpressure can be kept ready at hand for discharge in a ne spray overclothes or other objects and when the spray body is taken in the handand pressure is applied to the handle 20, the diaphragm valve will bereleased so that it is free toshift from its seat. This permits thewater to force its way from the channel I2 past the valve and into thechamber 6 to flow forwardly and be discharged through the nozzle .'I..As previously stated, as the water passes the spirally grooved plug 9,it will be given a rotating motion and will forward end of the chamber.A

While there has been shown a nipple 3 which is cast or otherwise formedintegrally with the body I, it is to be understood that there is nodesire to limit the construction of the spray evice to this specificdesign and it will be read ly apparent that other means may be employedf r attaching va hose or other fluid carrying pipe o the head as, forexample, as shown in Fig. 4. the body may have a short tube 21 insertedthereinto in alinementI with the water receiving passage which is hereindicated by the numeral I6', which will function in the place. of thenipple to be coupled with a hose or other fluid supply pipe.

What is claimed is:

A fluid discharge device, comprising a body having a forward end portionand having a water, chamber extending. longitudinally therethrough andcommunicating at one end in one portion of the body with an outlet, thebody being provided at the opposite end of the water chamber with arecess into which the water chamber opens, the bottom of the recessbeing provided with an annular channel encircling the chamber, thematerial of the body between the channel and the water chamber formingan annular valve seat, means for conducting iiuid into the annularchannel, a diaphragm valve disposed in the recess over the channel andsaid seat, means engaging the diaphragm at its periphery forestablishing a water-tight connection between such periphery and thewall of the recess at the outer side of the annular channel, a slotformed longitudinally in the side of the body and extending across butspaced from the outer side of the channel, the slot leading, at the endremote from the outlet, into the recess upon the side of the diaphragmaway from said outlet, a handle disposed within said slot and pivotallysupported for oscillation on an axis extending transversely of the body,the handle at one end having an inturned portion lying in the saidportion of the slot leading into the recess, a lingerextending from theinturned portion of the handle toward the'center of the diaphragm, apressure receiving element interposed between the finger and thediaphragm, and resilient means lyingin the slot beneath the handle andconstantly urging oscillation of the handle in a direction to move thesaid ngertoward the diaphragm to elect compression of the same againstthe seat.
